| Research Abstract |
For a hyperbolic knot in the 3-sphere, Dehn surgery yielding a non-hyperbolic 3-manifold is called an exceptional Dehn surgery. There are essentially three types of exceptional Dehn surgery. In this project, we focused on lens space surgery and toroidal surgery, and obtained various results. In particular, I gave an infinite family of hyperbolic knots admitting toroidal surgeries corresponding to three consecutive integers, and an infinite family of hyperbolic knots admitting lens space surgery between toroidal surgeries.
